Abstract

Pengetahuan tentang keberadaan air di landas pacu sangat penting untuk menjadi perhatian. Komite Nasional Keselamatan Transportasi (KNKT) menyatakan bahwa 32 % kasus kecelakaan penerbangan di Indonesia disebabkan karena licinnya landas pacu. Untuk dapat mengetahui potensi adanya genangan dibutuhkan sensor yang berfungsi untuk mengukur 2 parameter; curah hujan dan deteksi genangan air. Dengan menempatkan sensor curah hujan dan detektor genangan air, maka dapat diketahui pengaruh dari curah hujan dalam pendeteksian genangan air di landas pacu. Pada penelitian ini telah difabrikasi dan diimplementasi sensor curah hujan sebesar 0,128 + 0,052 mm dengan error terbesar sebesar 4,31 % di mana error dapat dipengaruhi faktor eksternal seperti angin. Hal tersebut ditunjukkan pada pengujian curah hujan di landas pacu di mana arah angin rata-rata yakni 35,8 % ke arah barat daya dengan kecepatan angin rata-rata 5,14 m/s saat pengujian. Sebaran hujan mempengaruhi pembacaan standing water detector di mana sensor bagian barat daya mendeteksi adanya genangan air terbesar bernilai 4,4 mm pada saat sensor lain hanya mendeteksi 1,1 mm. Konsumsi daya untuk sistem standing water detector selalu aktif adalah sebesar 10,37 Wh dan konsumsi daya untuk kondisi standby sebesar 0,96 Wh dan menghemat penggunaan energi sebesar 90,74 % jika dibandingkan dengan sistem selalu aktif. Untuk jangka panjang sistem aktivasi dengan curah hujan lebih efektif karena mampu mengoptimalkan penggunaan energi dan memperpanjang usia siklus pakai baterai aki.

Knowledge of the presence of water on the runway is very important to be a concern. The National Transportation Safety Committee (NTSC) stated that 32% of flight accidents in Indonesia were caused by the slippery runway. To be able to determine the potential for inundation, a sensor is needed to measure 2 parameters; rainfall and standing water detection. By placing a rainfall sensor and a standing water detector, it can be seen the effect of rainfall in detecting standing water on the runway. In this study, a rainfall sensor of 0.128 + 0.052 mm has been fabricated and implemented with the largest error of 4.31% where the error can be influenced by external factors such as wind. This is shown in the rainfall test on the runway where the average wind direction is 35.8% to the southwest with an average wind speed of 5.14 m / s during the test. The rain distribution affects the standing water detector measurements where the southwest sensor detects the largest standing water, which is 4.4 mm in value while other sensors only detect 1.1 mm. The power consumption for the always-active standing water detector system is 10.37 Watt-hour and the standby power consumption is 0.96 Watt-hour and saves energy usage by 90.74% when compared to the always-on system. In the long term, the activation system with rainfall is more effective because it can optimize energy use and extend the battery life cycle of the battery.
